PREFACE This e-book is an edited and reviewed collection of selected keynote papers addressed in the 1st and 2nd International Symposia on Processing and Drying of Foods, Vegetables and Fruits (ISPDFVF) held in Kuala Lumpur, Malaysia from 11th – 12th April 2011 and 18th – 19th June 2012, respectively. The symposiums were jointly organized between The University of Nottingham, Malaysia Campus and The Transport Process Research (TPR) Group of Prof. A.S. Mujumdar then located at the National University of Singapore and now at the Hong Kong University of Science & Technology. This symposium was initiated based on an idea initiated by Prof. Arun S. Mujumdar who is known globally as the Drying Guru within the research community. The first Symposium was also possible thanks to the tangible support provided by Drying Technology- An International Journal of which Prof. Mujumdar has been the Editor-in-Chief since 1988. Food processing has always been a major research area worldwide in various disciplines of science and engineering. It is an important part of the nexus of water, food and energy which are intricately interlinked and which will become increasingly important as shortages in all of these commodities will pose security issues in the future thanks to climate change. As a forum to discuss advancement in food processing technology, the ISPDFVF symposia also served as a platform to assemble academics, scientists, engineers, industrial experts and graduate students from various countries in the region to exchange and share their knowledge, ideas and findings in all aspects of food, vegetables and fruits processing, including drying and dehydration technologies. In this e-book, which can be freely downloaded and translated into different languages to enhance access, several topics are discussed on various key aspects of food processing, i.e. baking, drying, role of food antioxidants, food quality, physical and chemical analyses, and new processing techniques. The opening chapter in this e-book is a special paper presented by Prof. Arun S. Mujumdar entitled “On Academia-Industry Interaction: Perspectives on What It Takes to Succeed in R&D”. This paper addresses the main issues of R&D carried out by academia and problems associated with transferring the research findings to industrial practice. As industrial processing necessarily implies need to include industry personnel in relevant R&D projects, it is important to find ways of enhancing academia-industry interaction. Here, we would like to express our sincere appreciation to the contributing authors for their support and commitment in making this e-book published and available freely on-line to anyone anywhere in the world by visiting http://www.arunmujumdar.com/. We also would like to take this opportunity to thank the members of the International Advisory Committee and Local Organizing Committee, for successfully organizing the two Symposia and we hope this series will continue and succeed in future as well since the need for advances in this area will not diminish; in fact they will increase as the global population increases and the earth’s limited ability to provide resources require greater effort in coming decades. Finally, we would like to welcome proposals to write or edit useful e-books of global interest as part of the free e-book project initiated by Prof. Mujumdar. A number of books are already available at the e-books link of the above URL. More will become available in the near future. We hope readers of this series will contribute to this unique professional service whose impact cannot be valued as it is indeed invaluable.
